MUELLER WATER PRODUCTS REPORTS CYBERSECURITY INCIDENT ATLANTA, October 28, 2023 - Mueller Water Products, Inc. (NYSE: MWA) (“Mueller” or the “Company”) recently identified a cybersecurity incident impacting certain of its operational and information technology systems. The Company’s incident response team has implemented response and containment protocols and is working diligently to respond to and address this issue. Additionally, the Company has notified law enforcement and is communicating with its customers regarding the incident. Mueller is working with leading third-party cybersecurity specialists to support its investigation and recovery efforts. Although Mueller is working diligently with its third-party specialists on these efforts, the incident has caused and is expected to continue to cause delays in parts of the Company’s business operations that may adversely impact Mueller’s financial results. The investigation to assess the nature and scope of the incident remains ongoing and is in its early stages. Forward-Looking Statements This press release contains certain statements that may be deemed “forward-looking statements” within the meaning of the federal securities laws.

Actual results and the timing of events may differ materially from those contemplated by the forward- looking statements due to a number of factors, including, without limitation, ongoing assessment of the incident, legal, reputational and financial risks resulting from the cybersecurity incident and the Company’s ability to adequately assess and remedy the incident, the effectiveness of the Company’s business continuity plans during the incident, the Company’s ability to recover under its cybersecurity insurance policies, and the other factors that are described in the section entitled “RISK FACTORS” in Item 1A of the Company’s most recent Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (the “SEC”) on November 18, 2022, and later filings with the SEC on Form 10- Q.
